We (the CEA Events Team) recently posted about how we cut costs for EA Global last year. That's a big contributing factor, and involved hiring someone (a production associate) to help us cut overall costs.
It seems like you're making a few slightly different points:
I'm sympathetic to 1, but disagree with 2 and 3 for the reasons I outlined in my first comment.
I disagree that we should avoid discussing topics so as to avoid putting people off this community.[1]
Perhaps for some distasteful-to-almost-everyone topics, but this topic doesn't seem like that at all.
few people are thinking about how to navigate our way to a worthwhile future.
This might be true on the kinds of scales EAs are thinking about (potentially enourmous value, long time horizons) but is it not the case that many people want to steer humanity in a better direction? E.g. the Left, environmentalists, libertarians, ... ~all political movements?
I worry EAs think of this as some unique and obscure thing to think about, when it isn't.
(on the other hand, people neglect small probabilities of disastrous outcomes)
It seems plausible to me we might be approaching a "time of perils' where total x-risk is unacceptably high and will continue to be as we develop powerful AI systems, but might decrease later since we can use AI systems to tackle x-risk (though that seems hard and risky in its own myriad ways).
Broadly think we should still prioritise avoiding catastrophes in this phase, and bet on being able to steer later but low confidence.
Walking around the conference halls this February at EAG Global in the Bay Area, the average age seemed to be in the mid-20s or so.
The average age of EAG Bay Area 2025 feedback survey respondents was 30, FYI.
I don't think this removes the thrust of your questions, which I think are good and important questions, but people do seem to consistently underestimate the average age of EA Global attendees.
I learn about new ways that Julia had a significant impact on this community every few months, and it never ceases to give me a sense of awe and appreciation for her selflessness. EA would not be what it is today without Julia.
